Abstract

Las picaduras y resaltes que tienen una longitud de picadura de 3T, una longitud de resalte de *6T, una longitud de picadura de 7T, una longitud de resalte *3T, una longitud de picadura de 6T y una longitud de resalte de *7T, se forman alternativamente en un área de entrada en un área de pista en un disco optico como un patron de prueba para evaluar un error de lectura del disco optico. Este dato de patron de prueba se reproduce mediante un sistema de reproduccion para detectar un régimen de error, se adquiere un coeficiente de compensacion para reducir al mínimo el régimen de error, y se compensa una señal de reproduccion usando este coeficiente de compensacion de manera que la señal de reproduccion se reproduce con el régimen de error reducido al mínimo mediante el sistema de reproduccion.
